In the late cratonization phase from late Carboniferous to early Permian, the tectonic regime transformed from compaction to extension process in collision phase, the tectonic-magmatic activities were more and more strictly controlled by the new tectonic framework: the extensive development of continentalrift, eruption of volcanic rocks of double peak continental facies, massive intrusion of alkaline granite, upward invasion of basite and hyperbasite complex and diabase dike, accompanied by large-scale mineralization. Meanwhile, the products of magmatism evolved to silic and alkaline minerals.
